No matter what age, if a surgery has a high probability of making you look better than you would have without the surgery, for the rest of your life, -- and therefore make you feel better about yourself for the rest of your life -- then, in my opinion, it should be considered appropriate surgery. Beyond the surgeon offering surgery as an appropriate option, it should then be the adult's well-informed choice as to whether to have the surgery or not. However, some people have a self-perception disorder called "body dysmorphia syndrome" -- and unfortunately, some surgeons will do surgery on patients whether they believe the patient will actually look better or not. So what looks "better" can't be determined by either the patient or the patient's surgeon.The surgeon has to be able to dissociate, as best he/she can, their clinical judgement as to what would be "best" for the patient, from his/her desire to do surgery and to profit from it. In other words, each surgeon has to wear a "clinician's hat" and a "surgeon's hat" -- and wear ONLY the clinician's hat when helping you decide on whether to have surgery or not. In this regard, the surgeon should try to get into the head of and therefore present the opinion of the hypothetical "average person". I personally imagine corralling 100 people off the street at random and imagine them seeing you as you look now and as you will look after the surgery. If I sincerely believe that over 90% of them would say that you look better with the "after" result, then I offer the procedure as an option -- again, no matter what age.In considering the benefits of a facelift, it helps to place all your fingers in front of your ears and along your neck and push up and back. If it's obvious to you that you look better with this lifting maneuver, than a facelift just might be appropriate even at the age of 20. The main obstacle to you benefiting from a facelift in this situation is what your peers might think of you doing this relatively major procedure at such a young age -- something that may be a factor in your decision-making process or not.
